One wall ( stone and in-fill) of my barn gives onto a weather-proof annex.
In order to both add space and expose a very nice wall, I intend to insulate ( 200 mm fibre-wool) the exterior face of this wall ( 60 cm thick)
I started off by thinking I would put a vb on the outside face of the wall but then thought that the earth/lime whatever in the wall would certainly absorb any moisture and then re-vent it to the inside as and when.
Are my second thoughts correct ?
